The train line between Vinh and Dong Hoi to the south takes an inland route different from Highway 1, and there is some excellent scenery along the way. If you're travelling along the coast by bus, consider taking a break here and going by train.

Citadel. The only remaining parts of the citadel are the moat and three gates which can be seen on D Dao Tan where you can also find some drinking places which open up in the eveningedit

Cua Lo Beach. Cua Lo beach about 20 km outside of Vinh is an attractive stretch of sand backed up by some less attractive hotels and restaurants. It's more geared up for local visitors so can get quite busy during Vietnamese holiday periods. Outside of these times its pretty quiet and in the "winter" months you could have the beach to yourself. You can catch bus number 1 from Vinh (15,000 VD Dec 2012) which runs every hour. There are more frequent services during busier periods.edit
